Say (unto them, O Muhammad): Who provideth for you from the sky and the earth, or Who owneth hearing and sight; and Who bringeth forth the living from the dead and bringeth forth the dead from the living; and Who directeth the course? They will say: Allah. Then say: Will ye not then keep your duty (unto Him)? 31 So such is Allah, your True Lord; therefore what remains after the truth, except error? So where are you reverting? 32 Thus the word of your Lord has come into effect upon those who defiantly disobeyed - that they will not believe. 33 Ask them: "Is there among the partners (you ascribe to God) one who first originates then reverts it? Say: "It is God alone who first creates and then reverts it. So where do you stray?" 34 Say: "Does any of those beings to whom you ascribe a share in God's divinity guide unto the truth?" Say: "It is God [alone] who guides unto the truth. Which, then, is more worthy to be followed - He who guides unto the truth, or he who cannot find the right way unless he is guided? What, then, is amiss with you and your judgment?" 35 Most of them follow nothing but mere conjecture. But conjecture is of no use against the Truth. God is well aware of what they do. 36 This Qur'an is not such (a writ) as could be composed by anyone but God. It confirms what has been revealed before, and is an exposition of (Heaven's) law. Without any doubt it's from the Lord of all the worlds. 37 Do they say, "He has fabricated it?" Say, "Bring me one chapter like it. Call on whom you may besides God to help you, if what you say be true!" 38 Rather, they have denied that which they encompass not in knowledge and whose interpretation has not yet come to them. Thus did those before them deny. Then observe how was the end of the wrongdoers. 39 Of those some will believe and others will not. Your Lord knows best the mischief-makers. 40
